The soil matrix can impact the bioavailability of soil-bound organic chemicals, and this impact is governed in part by soil properties such as organic carbon (OC) content, clay minerals, and pH. Recently, a physiologically based extraction test (PBET) was developed to predict the bioavailability of soil-bound organic chemicals. In the current study, the bioavailability of phenanthrene (PA) from laboratory-treated soils varying in OC content, clay, and pH was investigated using an in vivo rat… CONTINUE READING
